It's very simple, so I don't think that video tutorial is necessary. Just replace the value after '#' with your value and that's all.
If you don't understand just tell me what do you want to change and I'll give you copy-paste solution.

1 more thing, Can i change Boots ID Color to make my boots have different color?
Like example my player wear generic boots with violet color when i change his boot to Nike Hypervenom with ID 180, his shoes not green black but violet white. So i think its possible to change shoes color if you know color ID?

So Cheat Engine ver. 6.5 is better for this table than ver. 6.6?
And valid means you need to do what? Be sure "know as" square ticked?

CE 6.5 is better for editing player names because you don't need to null terminate strings manually.
To make sure that pointer is valid just enter player profile who already got "Know as" name defined in database. Like "Pepe" from Real Madrit for example.
